I'm in the process of repairing this TNPA4782 SC board. I just need to find the specs for this one diode. D806 is marked 12- anyone know the specs or a suitable replacement?

Got it thanks! I've been trying to figure out how these markings codes work for these diodes. And there's a service manual for this board?Comment

Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.

Hi everyone!
I happened several times, in the search for help from the web, to consult this very interesting forum.
So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.
Having said that I come to the gist of my post on the forum as the title suggests.

Good day,
I have tried to remove BIOS supervisor password from Panasonic Toughbook CF-33 mk1. Model number CF-33AENABTG, unfortunately I don't have any other info.
I read the BIOS using afuwin, edited it and tried to flash new edited BIOS using afuwin. Unsuccessfully. Afuwin showed "Error: Problem erasing flash." starting with 0x00040000 and stoped. Then I tried many other options to flash BIOS from Windows without any luck. Finally i rebooted the device - and no post. Afterwards I have read the corrupted bios chip (MX25L12873F) using EZP2010 programmer.... -

In the Panasonic service manuals, both in the board schematics and in the part listing, the part numbers that are given are Panasonic part numbers instead of the actual part numbers.
This is especially annoying for small SMD components like diodes and transistors when you only have 1-3 digits printed on the component body.
For an example, look at the attached PDF.
Do you have a way to cross reference the Panasonic part number with the actual part number?
Thanks....07-03-2023, 08:16 PM
